Question

I’m using flask with a jinja2 template which includes another jinja2 template called buttons.html.

The parent of the buttons template looks like this:

{% include "{{ url_for('.buttons') }}" %}

The blueprint code looks like this:

@whatever_blueprint.route('/whatever/buttons.html', methods=['GET'])
def buttons():
    return render_template('/whatever/buttons.html')

This allows me to take advantage of the fact that jinja will resolve the . prefixed url_for path to the current blueprint context and thus give me buttons rendered specifically for the blueprint in which this is rendered. I use the .prefix method in other cases, but haven’t tried the nested url_for in this context. Unfortunately, I can’t seem to get this to work, presumably because of the nested {% {{ }} %}.

Is this possible?

Answer 1

Unfortunately (or fortunately? most use-cases would be rather ugly) you cannot include URLs but only templates.

What you want is {{ buttons() }} with buttons being the buttons function (or {{ buttons }} with buttons=buttons() in render_template()) passed to the render_template() call or made available via the global template context.
